Thoracic and retroperitoneal lymphatic injuries following spine surgery: illustrative cases.
Article in Journal of neurosurgery. Case lessons, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPostoperative lymphatic leakage is a rare complication of spine surgery caused by injury to the thoracic duct, cisterna chyli, or retroperitoneal lymphatic channels. Because of its rarity, diagnosis is often delayed and optimal management remains poorly defined. The authors present 3 illustrative cases and review current diagnostic and therapeutic strategies. OBSERVATIONS: A 66-year-old man developed a right chylothorax after posterior T2-3 corpectomy with costotransversectomy and cervicothoracic fusion for metastatic spinal cord compression. Following failed thoracic duct embolization, he underwent thoracoscopic ligation and talc pleurodesis with complete resolution. A 75-year-old man developed a retroperitoneal lymphatic leak after an aborted oblique lumbar interbody fusion (OLIF), which resolved with percutaneous drainage and dietary modification. A 70-year-old woman developed a symptomatic retroperitoneal lymphatic leak after staged multilevel OLIF and posterior deformity correction. Intranodal lymphangiography localized the leak and enabled successful embolization with n-butyl cyanoacrylate, avoiding reoperation. LESSONS: Lymphatic injury after spine surgery is uncommon but may occur after both thoracic and retroperitoneal approaches. Early recognition, biochemical confirmation, and multidisciplinary management are essential. Lymphangiography is central to diagnosis and treatment, although refractory cases may require surgery. Awareness of these complications may improve patient outcomes. https://thejns.org/doi/10.3171/CASE26792.
